Sean Owen commented on SPARK-14005:
-----------------------------------
I think we just discussed this? nonEmpty is just !isEmpty. takeRight and
reverse can be accomplished with sort and take. contains isn't going to be
efficient given the nature of an RDD.
I don't think RDDs are intended to be work-alikes for Scala collections.
